How to remember a variable on another page?

Question

Django

There are two pages. It is necessary that by pressing the top button select, a list of selected id from the table is transferred to the second page. How to implement it?


Function that displays 1 page
url(r'^show/$', views.show, name='show'),

def show(request):
    files = Files.objects.all().order_by('file')
    return render(request, 'show.html', locals())

Page function 2
url(r"^check/$", views.check, name='check'),

def check(req):
 # Мне нужно чтобы в этом месте значения из чекбокса сохранялись и я смог получить к ним доступ#
    return render(req, "check.html", locals())

I have implemented the functionality for selecting one file, when I press the select button in the table itself, there I pass the id from the checkbox and there are no problems

url(r"^check_one/(?P<file_id>\d+)$", views.check_one, name='check_one'),

Here is a function for checking one file, where 1 id goes

def check_one(req, file_id):
    file = Files.objects.get(file_id=file_id)
    if req.method == "GET":
        return render(req, "check_one.html", locals())
    if req.method == "POST":
        if 'edit' not in req.POST:
            if 'titul' in req.POST:
                check_titul(req, file, shab=req.FILES['shablon'])
                file = Files.objects.get(file_id=file_id)
            if 'all' in req.POST:
                check_all(req, file,shab=req.FILES['shablon'])
                file = Files.objects.get(file_id=file_id)
            if 'grafik' in req.POST:
                check_grafik(req, file,shab=req.FILES['shablon'])
                file = Files.objects.get(file_id=file_id)
            if 'plan' in req.POST:
                check_plan(req, file,shab=req.FILES['shablon'])
                file = Files.objects.get(file_id=file_id)
            if 'plan_svod' in req.POST:
                check_plan_svod(req, file,shab=req.FILES['shablon'])
                file = Files.objects.get(file_id=file_id)
            if 'comp' in req.POST:
                check_compititions(req, file,shab=req.FILES['shablon'])
                file = Files.objects.get(file_id=file_id)
        else:
            if 'edit' in req.POST:
                if 'titul' in req.POST:
                    edit_titul(req, file, shab=req.FILES['shablon'])
                    file = Files.objects.get(file_id=file_id)
                if 'all' in req.POST:
                    edit_all(req, file,shab=req.FILES['shablon'])
                    file = Files.objects.get(file_id=file_id)
                if 'grafik' in req.POST:
                    edit_grafik(req, file,shab=req.FILES['shablon'])
                    file = Files.objects.get(file_id=file_id)
                if 'plan' in req.POST:
                    edit_plan_svod(req, file,shab=req.FILES['shablon'])
                    file = Files.objects.get(file_id=file_id)
                if 'plan_svod' in req.POST:
                    edit_plan_svod(req, file,shab=req.FILES['shablon'])
                    file = Files.objects.get(file_id=file_id)
                if 'comp' in req.POST:
                    edit_compititions(req, file,shab=req.FILES['shablon'])
                    file = Files.objects.get(file_id=file_id)
        return render(req, "check_one.html", locals())
    else:
        return render(req, "check_one.html", locals())

As an option, you can najavascript id's, pass it to the next page and parse it there.
